2021. 5/28 FridayTime: 10:00 – 11:00
Speaker: An-Liang Cheng 鄭安良 (NCU, physics)
Title: Optimized Network Connection Models: Phase Transition and Frustration
In this talk, I will present my research about the optimized network model. First, I will briefly introduce the complex networks. Next, different optimized network models will be discussed. We consider network connection growing models that aim at minimizing the wiring cost while at the same time maximizing the network connections. Depending on the properties of the edge and node weight distributions, the system can exhibit a variety of phase transitions, including first-order, second-order and hybrid ones. I will also introduce the two-dimensional optimized networks with the bond crossing penalty. Mean field theory leads to the effective algorithms for finding the optimized network configurations in these models.
Dr. An-Liang Cheng received his Ph.D. degree from Physics Department, National Taiwan University. Now he is a postdoc at Statistical, Nonlinear and Bio Physics Research Group, National Central University.
